The NexStar Evolution 8 EdgeHD is a computerised 8-inch Schmidt-Cassegrain on a single-arm go-to mount, with StarSense AutoAlign and built-in WiFi. EdgeHD optics correct coma and field curvature across a flat field, which matters for astrophotography as well as visual use. The rechargeable battery runs about 10 hours, so it works away from mains power. It suits observers who want automated alignment and app control without a hand controller, and imagers who want a fast f/2 HyperStar path. It is heavier and more expensive than the standard Evolution 8, and the EdgeHD optics are the main reason to choose it over that model.

Owners rate the EdgeHD optics and StarSense alignment highly, calling the scope easy to set up and use for both visual and imaging work. Complaints centre on weight, the app-based control, and the premium over the standard Evolution 8.
The Celestron NexStar Evolution 8" EdgeHD with StarSense is a Schmidt-Cassegrain telescope with EdgeHD optics on a single fork arm, fully motorized go-to mount. The EdgeHD optics are flat-field and coma-free, and they carry StarBright XLT coatings. They are made for visual observing and for astro-imaging with cameras of all types, including DSLR and larger format CCD cameras.
StarSense AutoAlign aligns the telescope automatically when you tap Connect and Align in the SkyPortal app. Built-in WiFi connects the telescope to your smartphone or tablet, so the app controls it wirelessly. After alignment, you select an object in the app and the telescope goes to it. Mount modeling accepts up to 10 additional calibration stars for more precise pointing.
The Evolution mount has manual release clutches, precision machined worm gears on both axes, tray lighting and a USB charge port. It has 4 auxiliary ports, 2 on top of the fork and 2 on the bottom. A rechargeable lithium-iron phosphate battery provides up to 10 hours of continuous observing. The telescope is compatible with Fastar/HyperStar for imaging at f/2, and an optional Wedge for NexStar Evolution is available for longer exposures.
